%X This research proposes Cu, CuW and AgW for electrodematerials for micro-electro-discharge machining (micro-EDM),which are produced with block electrode on insulating Si3N4. Withthese electrodes, some trials were evaluated considering the EDMconditions. The machining properties were estimated by theremoval rate and tool wear ratio. The same phenomena are appliedat the micron level for micro machining. The conductive layer wasinvestigated on the micro-hole. This study aimed at the minimum ofdischarge energy to generate the conductive layer resulting tosuccess micro-EDM on insulating ceramics.
